“Applying the pop-up principle to greenhouses, Danish architect Simon Hjermind Jensen of SHJWORKS recently built The Invisible Garden House, a modular re-interpretation of the classic, glass-and-steel plant-growing typology. Designed for northern climates, the dome-like Invisible Garden House extends the growing season, and is naturally heated and cooled via a series of strategically-placed, operable openings at the top and bottom of the structures.

Built with lightweight yet strong polycarbonate panels sewn together, although the project currently sits on private property near Copenhagen, Jensen tells Fast Co.Design that he is aiming to take these easily assembled and easily reproduced greenhouses to the urban sphere as mini-gardens on the street or rooftops, to ‘take advantage of the gaps and in-between spaces created by the slower change of the city’s physical structure,’ thus testing ‘new structural concepts [and] pop-up functions which relate and connect to the existing urban fabric.'”
